Abstract
A non-electrical power operated sensor determining the position and movement of a first object in relation to a second object includes a valve on the first object. The valve has a housing and a cavity. A first sound device is mounted on one side of the housing and connected to the cavity. A second sound device is mounted on the other side of the housing and connected to the cavity. A piston connects the second object and the valve. The piston includes a push rod extending from one side of the plug body and the push rod being moved one way or another way causes one sound or another sound to be made. The disclosure also provides a monitoring system listening for the one sound or for the other sound, the system being able to instantly communicate with an electronic device of a user.
